Polishing device

ABSTRACT

A polishing device is disclosed. The polishing device includes a load seat and two polishing mechanisms mounted on the load seat. Each polishing mechanism includes a driving member and a polishing member driven by the driving member. The two polishing members of the two polishing mechanisms are oppositely received in the receiving space, and oppositely rotatable driven by the corresponding driving member. The polishing members are rotated oppositely, such that the new burs generated by one of the polishing members can be removed by other one of the polishing members at the same time.

BACKGROUND

1. Technical Field

The present disclosure relates to polishing devices, and particularly to a polishing device with a high work efficiency.

2. Description of the Related Art

A preform is usually formed with a plurality of burs. In a fine machining process, the burs are removed by a polishing device. Other burs may occur on edges of the machined preform along a cutting direction. Thus, the preform is needed to be polished again, which results in a low work efficiency.

Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION

FIGS. 1 through 3 show one embodiment of a polishing device 100. The polishing device 100 is configured for polishing a workpiece 200. In the embodiment, the workpiece 200 is moved to the polishing device 100 by a robot arm (not shown), and then polished by the polishing device 100. The workpiece 200 includes a bottom wall 20 and a sidewall 40 substantially perpendicularly extending from a periphery of the bottom wall 20. The bottom wall 20 includes a bottom surface 201. The sidewall 40 includes a side surface 203 perpendicularly extending from a periphery of the bottom surface 201 and a top surface 205 at a top of the sidewall 40.

The polishing device 100 includes a load seat 10, a first polishing mechanism 30, a second polishing mechanism 50, and a controller 60.

The load seat 10 includes a mounting member 11 and two support members 13. The mounting member 11 is substantially rectangular and plate-like. The two support members 13 are mounted on the mounting member 11 spaced apart from each other, and cooperatively define a receiving space 130. Each of the two support members 13 defines a fixing groove 1331 in a top thereof away from the mounting member 11, thereby forming a mounting portion 133.

The first polishing mechanism 30 has a substantially same structure as the second polishing mechanism 50. For simplicity, only the first polishing mechanism 30 is described in detail.

The first polishing mechanism 30 includes a driving member 31 and a polishing member 33. The driving member 31 is mounted on one mounting portion 133 in the corresponding mounting groove 1331. The driving member 31 includes a main body 311 and a driving shaft 313 connected to the main body 311. The main body 311 is securely received in the mounting groove 1331, and electrically connected to the controller 60. The driving shaft 313 is positioned in the receiving space 130. The polishing member 33 is securely connected to the driving shaft 313, and received in the receiving space 130. The polishing member 33 is substantially plate-like, and includes a base body 331 and a plurality of polishing pins 335. The base body 331 is substantially hollow cylinder, and connected to the driving shaft 311. The polishing pins 335 are mounted on a periphery of the base body 331 and spaced apart from each other, thereby forming a polishing surface 3351 away from the base body 331. The polishing member 33 is driven to rotate clockwise by the driving member 31, such that the side surface 203 and the top surface 205 are polished by the polishing surface 3351, thereby removing burs on the side surface 203 and the top surface 205. At the same time, new burs are clockwise generated by the polishing member 33. In the embodiment, the polishing pins 335 are made of nylon material. In other embodiments, the polishing pins 335 can be made of wool. The polishing member 33 can be grinding wheel.

The second polishing mechanism 50 includes a driving member 51 and a polishing member 53. The driving member 51 is mounted on the other mounting portion 133 in the other mounting groove 1331. The driving member 51 is electrically connected to the controller 60. The polishing member 53 is connected to the driving member 51, and opposite to the polishing member 33 of the first polishing mechanism 30. The polishing member 53 is driven to rotate counterclockwise by the driving member 51, such that the new burs are removed. In other embodiments, the first polishing mechanism 30 can rotate counterclockwise, and accordingly, the second polishing mechanism 50 can rotate clockwise, as long as rotation directions of the first polishing mechanism 30 and the second polishing mechanism 50 are opposite.

The controller 60 is placed adjacent to the load seat 10, and is electrically connected to the first polishing mechanism 30, the second polishing mechanism 50, and the robot arm, thereby controlling the robot arm to move relative to the first polishing mechanism 30 and the second polishing mechanism 50, and the first polishing mechanism 30 and the second polishing mechanism 50 polish.

In use, the workpiece 200 is moved to the polishing device 100 by the robot arm. The polishing members 33, 53 are rotated oppositely, and the workpiece 200 is moved relative to the polishing members 33, 53, such that the side surface 203 and/or the top surface 205 are polished.

The polishing members 33, 53 are rotated oppositely, such that the new burs generated by one of the polishing members 33, 53, can be removed by other one of the polishing members 33, 53 at the same time. Other polishing processes can be omitted. Thus, a polishing efficiency is improved.
